The Crittall Experience


RITTALL Windows has a long and proud history and its core

values of trust, honesty and respect are as strong today as they were

when the company was founded more than 160 years ago.

This brochure will give you a comprehensive view of Crittall’s offer to

the client, architect and contractor. It provides details of the many-

faceted service that Crittall Windows can provide as well as a host of

examples of high-status projects completed both in the UK and the

United States.

You will also find details of the newly-revised Building Regulations

and how they permit the use of Crittall steel windows with

confidence.

Crittall Windows is proud to have been granted the Queen’s

Award for Enterprise in International Trade in 2010.

“This is in effect an award for excellence in how we have

gone about our business,” says Managing Director John

Pyatt. “Everything is taken into account – employment

practices, environmental policy, and our work with the local

community – as well as our export achievements.”

The prestigious Queen’s Award has been granted in specific

recognition of the company’s achievements in the American

market, details of which appear on Pages 16 and 17 of this

brochure.

RITTALL is the world’s oldest supplier of steel

windows and has been in continuous operation

for more than 160 years. The company was set

up in Braintree, Essex, in 1849 by Francis Berrington

Crittall and the family remained directly connected with

the firm, through successive generations, until 1974.

An early prestigious contract in the mid 1880s was to

supply the metal windows for the Houses of Parliament

and the Public Record Office. The company expanded

abroad, opening subsidiaries or forming partnerships in

the USA, South Africa, Australia, Nigeria, China and

Germany where, among other contracts, it supplied the

fenestration for the Bauhaus.

In 1939 the company opened its first galvanising plant at

Witham, Essex, and in 1964 developed a process for pres-

sure testing the weathertightness of windows, leading to

the creation of a new British Standard. The first polyester

powder coated windows were developed in 1977 and a

year later Crittall celebrated the production of its 50 mil-

lionth steel window.

New officesThe 1990s proved a busy time for the company which

moved at the start of that decade into new offices with a

new factory, still in Braintree. Three years later the

Corporate 2000 range of windows was introduced and in

the following four years there were two changes in owner-

ship, the latter being the company’s purchase by Marmon

Corporation of Chicago. That year, 1997, also witnessed the

introduction of the Berkeley range for a prestigious con-

tract at Yale University.

The company changed hands again before a management

buyout in 2004, followed in 2007 by a move to new offices

and factory at Witham. Throughout these challenging

times the company maintained a loyal and productive

workforce with one in ten employees to date having been

with the firm for more than 40 years.

Achievements recognisedAll these achievements were recognised and crowned in

2010 when Crittall Windows was awarded a Queen’s

Award for Enterprise in International Trade.

HE first-known application in the world of a particular low energy strategy in a

city centre building has been assisted by the specification of Crittall windows in

a new building in Taviton Street, Bloomsbury, to house the University’s Slavonic

Studies and East European School (SSEES). The Corporate 2000 range was specified for

the exterior of the new building and internally Crittall Corporate W20 profiles were used

in a magnificent six-storey atrium that allows light to permeate through the building that

is naturally ventilated all year round and passively cooled during the summer months. It

engages downdraught cooling via the central light well through peak periods of summer

several listed Georgian terraces also used by the University.

HE steel windows in the 1966-vintage Heinz Wolff building at Brunel

This was a complete like-for-like replacement in order to maintain the architec-

tural integrity of both the building and the campus of which it forms a part but with the

new windows equipped with double glazing. Not only do the new windows meet aes-

thetic requirements but also the narrow sightlines made possible by the strength of steel

mean that large window areas could be maintained in the building that houses the uni-

customised modern interior has been created in the headquarters of the

Burberry Group in Horseferry House, Westminster, but the exterior of the

1930s building has retained its original appearance thanks to the installation of

Crittall Corporate W20 profiles. The windows match the original fenestration as required

by the strict planning schedules of Westminster City Council. Small pane detail has been

replicated in the eight-storey 160,000 sq ft building. Crittall also supplied bespoke glazed

steel screens for the interior office spaces so as to ensure that the refurbishment created a

light and modern office environment assisted by the original lightwells which have been

utilised as daylit circulation spaces.

HE £1.8 million contract to replace 1500 windows and balcony screens at Grade

HE Grade II listed art deco building that once housed Derry and Tom’s

department store in Kensington High Street was transformed into the new

headquarters of Sony Music Entertainment. Internal steel glazed doors and

partitioning from Crittall Windows’ Corporate W20 range played a significant role in

transforming the third and fourth floors of the building to create an open plan warehouse-

style office for 450 employees. The galvanised glazed screens separate various

departments within the offices while ensuring that light can flow around the large interior

spaces. The galvanising reinforced the industrial feel suited to a warehouse character

sought by the designer.

HE fashionable Soho Hotel, part of the Firmdale hotel Group, opened in

flexibility in design which was used by architect Peter French to maximize the glazing

in the main façade: a major feature of the building. Steel was chosen to meet with

planning requirements and to complement the surrounding buildings in the area. The

use of glass as a design medium in its own right, complements the style of construction

with the slim sightlines characteristic of steel windows adding to the overall aesthetics.

Part L Regulations and protecting the environmentMeeting the latest Building Regulations.

Crittall Windows has played a full and active role in the

Governments consultation on the revision of Part L of

the Building Regulations (Conservation of Fuel and

Power) that came into force in October 2010.

As a result, architects and designers can continue to

specify Crittall Windows’ products secure in the

knowledge that they may be used in a variety of ways that

satisfy the requirements of the revised Part L. (See Table

opposite for indicative U-values of window and door

components).

Heritage buildingsMuch of Crittall’s work involves installation in

heritage buildings. The new

Regulations (Part L1B for

Existing Dwellings and Part

L2B for Existing Buildings

Other Than Dwellings) both

allow exemptions in the case of

heritage buildings. These

exemptions apply if compliance

with the new energy efficiency

requirements would alter the character or appearance of

heritage buildings or even risk a deterioration of the

building fabric.

For existing dwellings and existing non-dwellings the

exempt buildings are as follows:

� Listed in accordance with section 1 of the Planning

(Listed Buildings and Conservation Areas) Act 1990:

� in a conservation area designated in accordance

with section 69 of that Act; or

� included in the schedule of monuments

maintained under section 1 of the Ancient

Monuments and Archaeological Areas 1979

Also exempt are:

� buildings which are of architectural and historical

interest and are covered in a local authority’s

development plan or local development framework;

� buildings which are or architectural and historical

interest within national parks, areas of outstanding

natural beauty etc;

� buildings of traditional construction with

permeable fabric that both absorbs and readily allows

the evaporation of moisture.

Guidance issued by English Heritage should be taken into

account and Building Control Officers are now instructed

by the regulations to take account of the views of the local

authority conservation officer.

Full details of how Crittall Windows comply are

available from the company (see back cover for details)

Building Regulations Part F covers means of ventilation.

Trickle ventilators are not required in all replacement

windows but all Crittall windows can be fitted, if required,

with suitable trickle vents. The work must not adversely

affect the character or appearance of the building.

In partnership with MLM Building Control Ltd, a wellrespected Corporate Approved Inspector, Crittall Windowsoffers an advisory service that gives guidance to professionals

seeking planning and building control approval. Additionally, through MLM,Crittall is also able to obtain Building Control. Approval for projects as awhole. To ensure the process of obtaining Building Control Approval forreplacement windows is swift and straightforward, Crittall steel windowshave been ‘Type Approved’ by MLM Building Control for compliance withthe new Part L 2010 (Conservation of Fuel & Power) Building Regulation.With this knowledge, clients can be assured that Crittall Windows are fullycompliant with Part L of the Building Regulations and can be used withconfidence for both replacement window projects and new-build schemes.

Concern for the environment is a fundamental aspect of Crittall’s corporate business

strategy. It has demonstrated this concern throughout its manufacturing processes and

designs which strive to minimise environmental effects by using safe and sustainable

resources and wherever possible to manufacture products from materials that are capable

of being recycled.

The principal components of a Crittall window are steel and glass which are the most

recyclable building materials in use. Steel is a unique material because it always contains

100% recycled steel in its manufacture. Crittall also reclaims the steel and glass from old

windows when replacing them with new products.

The company operates within the constraints of BS EN ISO 14001:2004 a recognised

international environmental management standard that sets targets for solids, liquids,

gaseous emissions and waste generation. In the manufacturing process Crittall minimises

the creation of waste, especially hazardous waste, and disposes of all wastes though safe

and reasonable methods, which are in compliance with all relevant legislation, and it

controls the discharges of effluent to sewers and ground water, as required by regulation.

Crittall extends its environmental concern to its key suppliers and contractors and

reviews their credentials as well.

Because of their inherent strength, steel windows have much thinner frames than is

possible with other materials. This lets in more daylight thus reducing the use of artificial

lighting in the buildings in which they are installed.

and commercial steel windows‚

International

HE crowning achievement of Crittall’s export business was the award

in 2010 of a Queen’s Award for Enterprise in International Trade. This

was in recognition of its success in the notoriously difficult American

market where the company has seen the value of its sales increase by a

significant amount in recent years.

Crittall is now the second largest supplier of steel windows in the United States

having rebuilt its entire distribution network there in the six years since the

management buyout.

For more than a decade Crittall has been the preferred supplier for replacement

windows in an historic New York landmark: 300 Central Park West in the heart

of Manhattan. The company supplied the original windows in the 1931 luxury

apartment block and so was the natural choice to furnish replacements from its

Homelight range. Crittall still had to satisfy the stringent requirements of the

New York City Landmarks Preservation Commission concerning restoration of

the façade but, thanks to its reputation for the highest quality products and its

long connection with America, it was easily able to do so.

DOWNTOWN New York’s new luxury hotel is owned by the Firmdale Group,

which also owns the London Soho Hotel where Crittall Corporate W20 and

Corporate 2000 profiles were used throughout. It was the success of that UK

project that led Firmdale to turn once more to Crittall to provide the

fenestration at Crosby Street, NYC (pictured below). The final design

incorporates a dramatic rectilinear facade of brick, framing 54 large New York

loft style floor-to-ceiling height Corporate

W20 steel windows, which allow the

maximum amount of natural daylight to flood

the rooms.

The dark-green Crittall profiles include an

unusual 24-pane configuration with a central

pivotal four-pane opening light, double

extremely low U-value resulting in excellent

energy efficiency.
